Abstract

This paper examines the potential of a numerically derived CPT-based formulation for p-y curves in sand (Suryasentana & Lehane 2014) to predict the response observed in lateral load tests conducted on six piles in four different sand deposits. A summary of the methodology employed in the derivation of this formulation is first described before presenting information related to each of the case histories examined. The lateral load displacement data measured in these case histories are shown to compare well with predictions obtained using the p-y formulation. This agreement should encourage further refinement of the formulation and ultimately the direct use of CPT qc profiles for the analysis of laterally loaded piles in sand.
